  • Publication number: 20160282829
    Abstract: A controller includes a control computation unit, a control computation output correction unit, and a final-control-element output upper-lower limit processing unit. The control computation unit calculates, for each control cycle, a control computation output value by performing a control computation using a controlled variable and a set point as input values. The control computation output correction unit corrects the control computation output value to a predetermined final-control-element output upper limit in a case where the control computation output value is equal to or larger than a predetermined threshold A. The final-control-element output upper-lower limit processing unit outputs to a control target a value obtained by limiting the corrected control computation output value to a value that is equal to or larger than a predetermined final-control-element output lower limit and that is equal to or smaller than the final-control-element output upper limit, as a final-control-element output value.
